This includes information about PHP compilation options and extensions, the PHP version, server information and environment (if compiled as a module), the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License.
Because every system is setup differently, phpinfo() is commonly used to check configuration settings and for available predefined variables on a given system.

| 5.2.2 | The "Loaded Configuration File" information was added, when before only "Configuration File (php.ini) Path" existed. |
Examples
Example #1 phpinfo() Example

// Show all information, defaults to INFO_ALL

// Show just the module information.
// phpinfo(8) yields identical results.
